Raleigh, NC—The web-development world is buzzing about the latest release of Rails: Rails 3 is a huge step forward. You can now easily extend the framework, change its behavior, and replace whole components to bend it to your will, all without messy hacks.

Author and Rails Core developer José Valim guides you through seven different tutorials, each of them using test-driven development to build a new Rails extension or application that solves common problems with these new APIs. You will understand how the Rails rendering stack works and customize it to read templates from the database while you learn how to mimic Active Record behavior, like validations, in any other object. You will find out how to write faster, leaner controllers, and you'll learn how to mix Sinatra applications into your Rails apps, so you can choose the most appropriate tool for the job. In addition, you will improve your productivity by customizing generators and responders.

This book will help you understand Rails 3's inner workings, including generators, template handlers, internationalization, routing, and responders. With the knowledge you'll gain, you'll be ready to tackle complicated projects more easily than ever before, creating solutions that are well-tested, modular, and easy to maintain.

Available in epub, mobi, and PDF direct from the publisher and in paperback from fine bookstores worldwide.
